Emergency call alarm systems for freezer rooms

 

 

The emergency call alarm systems for freezer rooms consist of a main unit, sirens, and up to 4 lighted trigger points. Emergency call equipment is communications equipment by means of which the necessary help can be summoned and sent to the place of use. Even in freezer rooms, emergencies can occur and risk to human life may arise.

 

 

Properties

  • Main unit with floating relay contact, including storage battery to guarantee function in case of a mains failure, with LED displays for personnel alarm, technical alarm, mains operation, and storage battery operation
  • Up to 4 palm buttons can be connected
  • Optical alarm via LED display on main unit
  • Acoustic alarm 103 dB
  • Palm button including illuminated indicator and LED lamp
  • Electronic siren in the plastic casing

 

Operations

 

The personnel emergency call is triggered by a palm button, which is available in two designs. The alarm is forwarded audibly via the sirens and visibly via a relay contact on the main unit. A flashing light for an additional optical alarm can be connected to the main unit. The palm buttons are lighted in case of darkness. Power is supplied from the main unit with an installed storage battery and charge controller. The function of the emergency call alarm system is thus guaranteed, even in case of a mains failure.

The personnel alarm can be extinguished by the employees themselves only by unlocking the palm buttons.
